Several years ago while needing a hand holding up the rear of the transmission on my van I grabbed a scissors jack out of my wife's car and it worked great. Since then I have used it many times and even made some little adapters to make it round object better. When she traded the car I kept her jack. Just finished using it to hold a garbage disposal in place while I tightened the retaining ring....This would be no great feat except I have pulled a muscle in my back and have been having muscle spasms for about 4 days. Plumber bill would have been about $100USD for maybe 20 minutes worth of work. Dont think the plumber could have done it any easier than this .
